the inside of both front tires are balding about an inch wide, the drivers side a little worse then the passenger side? 2004 f-350 dually 235-75-16 tires, only about 1000 miles on them. this happended to the last pair i bout as well. any help?

 

Well you have a frontend, or alingment problem

 

i had a front end alignment done, it fixed it but bout 3,000 miles later again it happened

 

Id take it back to the place you had the allignment done. It has to be covered under some kinda guarantee??? Like 1 year or maybe a 10k mile? Sounds like you may have serverly worn tie rods or they were not tightened down right. They should also replace the tires since they obviously didnt fix the the allignment.

I would say you either have a bad or bent tie rod end. Or it could be the King pin bearings.

 

Ball joints or wheel bearings
